I recall being a bit bored with the Atmos album too. But the Live in Tehran concert is discrete 5.1 and I really enjoyed it. Maybe seeing the musicians doing their thing helped. Synths and percussion.I listened to the Atmos portion of Schiller - Morgenstund. Sadly, it's not really my cup of tea musically speaking. To be honest I was bored even with the improved spread of Atmos as it's just kind of bland electronic music without a real beat half the time. It starts out with some nice circular sounds around the room, but eventually seems to hang out more in the front overall than Booka Shade. Maybe it will get better with a couple more listens, but I wouldn't bet on it. I watched some of the videos and the "Berlin Tehran" one was excellent. The same track in Atmos was boring. I don't know. I was disappointed.
I recommend checking out the Tehran show, for those that might have went straight for the album and haven't gotten around to the extras.
